The use of dexamethasone in oral cancer patients with microvascular reconstruction did not provide a benefit. More major complications, especially infections, occurred in patients receiving dexamethasone. Our data thus do not support the use of peri- and postoperative dexamethasone in oropharyngeal cancer patients undergoing microvascular reconstruction.

This study suggests that the relation of periodontal infection to the systemic inflammatory condition is more complicated than previously presumed. The findings of this study suggest that the possible systemic effect of periodontal infection is dependent on serum lipid composition.

BackgroundThe aim was to clarify the occurrence of delayed union after surgical treatment of mandibular fracture and investigate whether an association exists between perioperative use of dexamethasone and delayed union.Material and MethodsThirty-seven patients were included in a prospective randomized study. Of these patients, 19 (51.4%) were randomized to receive a total dose of 30 mg of dexamethasone and 18 (48.6%) served as controls. Patients underwent clinical and radiological investigation immediately, one month, three months and six months postoperatively. Radiographs were evaluated by an experienced, blinded senior oral radiologist.ResultsDelayed fracture union was found in 9 patients (24.3%). It was associated significantly with angle fractures (p=0.012). Delayed union occurred more frequently in patients who received dexamethasone (36.8%) than in those who did not (11.1%) (p=0.068). The association of infection with delayed union was significant (p=0.027). Moreover, dexamethasone was significantly (p=0.019) associated with delayed fracture union with concomitant infection. Gender, age group, smoking habit, treatment delay and duration of surgery were not associated with delayed union.ConclusionsInfection was associated with delayed union. Short-term high-dose dexamethasone predisposed to complicated fracture union, especially in patients with angle fractures. The relationship between dexamethasone and delayed bone healing without infection remains unresolved. Key words:Mandibular, radiology, fracture union, dexamethasone.

The only benefit of perioperative dexamethasone use was lower total oxycodone dose; however, the disadvantages were greater. Because dexamethasone can have adverse effects on the postoperative course, routine use of dexamethasone as a pain or nausea medication during reconstructive head and neck cancer surgery is not recommended.
